Seiko Instruments Inc. 1
The S-808xxC series is a series of high-precision voltage detectors developed using CMOS process. The
detection voltage is fixed internally with an accuracy of ±2.0%. Two output forms, Nch open-drain and CMOS
output, are available. Super-low current consumption and miniature package lineup can meet demand from the
portable device applications.
Features
• Super-low current consumption 1.3 μA typ. (detection voltage≤1.4 V, at VDD = 1.5 V)
0.8 μA typ. (detection voltage≥1.5 V, at VDD = 3.5 V)
• High-precision detection voltage ±2.0%
• Operating voltage range 0.65 V to 5.0 V (detection voltage≤1.4 V)
0.95 V to 10.0 V (detection voltage≥1.5 V)
• Hysteresis characteristics 5% typ.
• Detection voltage 0.8 V to 6.0 V (0.1 V step)
• Output form Nch open-drain output (Active Low)
CMOS output (Active Low)
• Lead-free, Sn 100%, halogen-free*1
*1. Refer to “ Product Name Structure” for details.
Applications
• Battery checkers
• Power failure detectors
• Power monitor for portable equipments such as pagers, calculators, electronic notebooks and remote
controllers.
• Constant voltage power monitor for cameras, video equipments and communication devices.
• Power monitor for microcomputers and reset for CPUs.
Packages
• SC-82AB
• SOT-23-5
• SOT-89-3
• SNT-4A

Operation
1. Basic Operation: CMOS Output (Active Low)
1-1. When the power supply voltage (VDD) is higher than the release voltage (+VDET), the Nch transistor is
OFF and the Pch transistor is ON to provide VDD (high) at the output. Since the Nch transistor N1 in
Figure 17 is OFF, the comparator input voltage is CBA

++
•+ .
1-2. When the VDD goes below +VDET, the output provides the VDD level, as long as the VDD remains above
the detection voltage −VDET. When the VDD falls below −VDET (point A in Figure 18), the Nch transistor
becomes ON, the Pch transistor becomes OFF, and the VSS level appears at the output. At this time
the Nch transistor N1 in Figure 17 becomes ON, the comparator input voltage is changed to
BA

+
•.
1-3. When the VDD falls below the minimum operating voltage, the output becomes undefined, or goes to the
VDD when the output is pulled up to the VDD.
1-4. The VSS level appears when the VDD rises above the minimum operating voltage. The VSS level still
appears even when the VDD surpasses −VDET, as long as it does not exceed the release voltage +VDET.
1-5. When the VDD rises above +VDET (point B in Figure 18), the Nch transistor becomes OFF and the Pch
transistor becomes ON to provide VDD level at the output.

Technical Terms
1. Detection Voltage (−VDET), Release Voltage (+VDET)
The detection voltage (−VDET) is a voltage at which the output turns to low. The detection voltage varies slightly
among products of the same specification. The variation of detection voltage between the specified minimum
(−VDET) Min. and the maximum (−VDET) Max. is called the detection voltage range (Refer to Figure 21).
Example: For the S-80815CN, the detection voltage lies in the range of 1.470≤(−VDET)≤1.530.
This means that some S-80815CNs have 1.470 V for −VDET and some have 1.530 V.
The release voltage (+VDET) is a voltage at which the output turns to high. The release voltage varies slightly
among products of the same specification. The variation of release voltages between the specified
minimum (+VDET) Min. and the maximum (+VDET) Max. is called the release voltage range (Refer to Figure
22). The range is calculed from the actual detection voltage (−VDET) of a product and is expressed by
−VDET×1.03≤+VDET≤−VDET ×1.08.
Example: For the S-80815CN, the release voltage lies in the range of 1.514≤(+VDET)≤1.652.
This means that some S-80815CNs have 1.514 V for +VDET and some have 1.652 V.

Remark Although the detection voltage and release voltage overlap in the range of 1.514 V to 1.530 V,
+VDET is always larger than −VDET.
2. Hysteresis Width (VHYS)
The hysteresis width is the voltage difference between the detection voltage and the release voltage (The
voltage at point B −The voltage at point A =VHYS in Figure 18). The existence of the hysteresis width
prevents malfunction caused by noise on input signal.
3. Through-type Current
The through-type current refers to the current that flows instantaneously at the time of detection and release
of a voltage detector. The through-type current is large in CMOS output products, small in Nch open-drain
output products.
4. Oscillation
In applications where a resistor is connected to the voltage detector input (Figure 23), taking a CMOS active
low product for example, the through-type current which is generated when the output goes from low to high
(release) causes a voltage drop equal to [through-type current]×[input resistance] across the resistor. When
the input voltage drops below the detection voltage (−VDET) as a result, the output voltage goes to low level.
In this state, the through-type current stops and its resultant voltage drop disappears, and the output goes
from low to high. A through-type current is again generated, a voltage drop appears, and repeating the
process finally induces oscillation.

Precautions
• Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in
electrostatic protection circuit.
• In CMOS output products of the S-808xxC series, the through-type current flows at the detection and the
release. If the input impedance is high, oscillation may occur due to the voltage drop by the through-type
current during releasing.
• In CMOS output products oscillation may occur when a pull-down resistor is used, and falling speed of the
power supply voltage (VDD) is slow near the detection voltage.
• When designing for mass production using an application circuit described herein, the product deviation and
temperature characteristics should be taken into consideration. SII shall not bear any responsibility for the
products on the circuits described herein.
• SII claims no responsibility for any and all disputes arising out of or in connection with any infringement of the
products including this IC upon patents owned by a third party.

Caution The above connection diagram and constants do not guarantee correct operation. Perform
sufficient evaluation using the actual application to set the constants.
Application Circuit Examples
1. Microcomputer Reset Circuits
If the power supply voltage to a microcomputer falls below the specified level, an unspecified operation may
be performed or the contents of the memory register may be lost. When power supply voltage returns to
normal, the microcomputer needs to be initialized before normal operations can be done.
Reset circuits protect microcomputers in the event of current being momentarily switched off or lowered.
Reset circuits shown in Figures 27 to 28 can be easily constructed with the help of the S-808xxC series,
that has low operating voltage, a high-precision detection voltage and hysteresis.

In Nch open-drain output products of the S-808xxC series, detection voltage can be changed using
